Power Line: Sunni terrorists "boxed out"

John Hinderaker at Power Line blog makes a fundamental point about the shifting basis for Islamic terrorism:

With Hezbollah's mini-success in Lebanon, and Iran's success in subsidizing Hezbollah and moving towards the development of nuclear weapons, it has become the conventional wisdom that the Shiites have surpassed the Sunnis as the main threat to the West. Less note is made of the reason why the Sunnis seem to be lagging--the fact that they have no major state sponsoring their terrorism and their development of weaponry. Even less note (none that I'm aware of) is made of the reason why the Sunnis lack such a state--the overthrow by the U.S. of the Taliban in Afghanistan and of Saddam Hussein in Iraq.

I would only add that the comparison is hopefully between radical Sunnis and radical Shiites.
